DANIEL P. BOSVVORTH, OF MARIETTA, OHIO, ASSIGNOR OF ONE-HALF TO ZEBEDEE COMPTON, OF MARIETTA, OHIO.

METALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 768,008, dated August 16, 1 904.

Application filed June 13, 1904. Serial No. 212,402. (No model.) 7

To all whmn it ntcty concern:

Be it known that I, DANIEL P. BoswoR'rH, a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented certain new and useful I Improvements in Metallic- Railway-Ties, of

common to many metallic ties, is toavoid the use of spikes to secure the rails upon the tie,

the entire operation of securing the rails being done by means of wrenches acting upon the various bolts and screws which hold the parts together in position.

I accomplish the objects aforesaid by constructing and associating the parts as illustrated in the accompanying drawings, of

' which Figure 1 is atop plan view, and Fig. 2 is a side view. The rails are shown in section in Fig. 2. Y

Throughout the drawings like letters refer to like parts The letter A marks a base-plate, shown in the drawings as a flat piece of metal extending across the track beneath the rails. I do not desire to be understood as limiting myself to the exact flat shape illustrated, as there are many commonhollow forms given to metallic ties which could obviously be substi tute-d for the flat plate. For purposes of this description the plate formis sufficient,

The letters B and O designate, respectively, the angle-irons arranged outside and inside of the position of the rail and secured to the plate A by rivets D or in like manner. Through angle-irons B and O and through the plate A are holesb and c for use when the plate A is to be fixed upon the stringers of a bridge by bolts or similar attaching devices.

Any suitable means for securing the plate where desired may be substituted, and the holes arenota feature of my invention.

Arranged next within the angle-irons mentioned above are the channel-irons E, one side of each being marked F, and the other side designated by the letter Gr. Through the sides F are set-screws H, and fitting between the two channel-irons E is another channeliron having perpendicular sides and which may be termed the chair J, as it directly supports the rail K, as illustrated. The upper sides F of the channel-irons E grasp the flange of the rail, and their lower sides Gr rest upon plate A. The set-screws I-I hold the rail firmly upon the chair J.

Twin bolt-rods L run transversely across thetrack above plate A and beneath the rails, passing through angle-irons B and O, through the channel-irons E, and through the two perpendicular sides of the chair J. Nuts Z upon the threaded ends of the. bolt-rods clamp all the parts together, and it will be noted that the track can be laid and taken up by theuse of a wrench only, and no sledge or hammer work is called for. It will be observed, furthermore, that each part departs but little from common shapes turned out by rolling-mill machinery, and this fact renders the construction of the parts less costly than where special machines wouldneed to be designed and built for the purpose.

I am awarethat other metallic ties are made which may be put together and taken down solely by means of wrenches, and I do not claim that feature as my invention.

Having thus described my invention and its mode of operation, what I claim is 1. In a metallic railway-tie, the combination with a base, of the angle-irons secured to the base, the channel-irons arranged between said angle-irons and havingone side adapted to grasp the flange of a rail, a chair located between the said channel-irons and adapted to support a rail, and clamping devices whereby the said parts above the base and below the rail may be secured together.

2. In a metallic railway-tie, the eombination with a base, of the angle-irons secured to the base, the channel-irons arranged between said angle-irons and having one side adapted to grasp the flange of a rail, a chair J located between the said channel-irons and adapted to support a rail, and clamping devices whereby the said parts above the base and below the rail may be secured together.

3. In a metallic railway-tie, the combination with a base, of the angle-irons secured to the base, the channel-irons arranged between said angle-irons and having one side adapted to grasp the flange of a rail, a chair located between the said channel-irons and adapted to support a rail, and the transverse bolt-rods passing through the said angle-irons, channel-irons and chair whereby the said parts above the base and below the rail may be secured together.

4. In a metallic railway-tie, the combination with a base, of the angle-irons secured to the base, the channel-irons arranged between said angle-irons and having one side adapted to grasp the flange of a rail, a chair J located between the said channel-irons and adapted to support a rail, and the transverse bolt-rods passing through the said angleirons, channel-irons and chair whereby the said parts above the base and below the rail may be secured together.

5. In a metallic railway-tie, the combination witha base, of the angle-irons secured to the base, the channel-irons arranged between said angle-irons and having one side adapted to grasp the flange of a rail, a chair located between said channel-irons and adapted to support a rail, the screws vH through said side of the channel-irons by which the rail is pressed downwardly upon said chair, and clamping devices whereby said parts above the base and below the rail may be secured together.

In testimony whereof I afiix my signature in presence of two witnesses.

DANIEL I. BOSWOR'IH.
